LED XLAMP WHITE SMD XRCWHT-L1-0000-002B7 Equivalent & Substitute Parts

Part Overview

The XRCWHT-L1-0000-002B7 is an XLamp® XR-C series white LED from CreeLED, Inc., designed for surface mount applications in the 3529 (9073 Metric) package. This component delivers 43 lumens at 350mA test current with a forward voltage of 4.6V and a 90° viewing angle. The product is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and production continuity. The XR-C series has been superseded by newer generations, requiring engineers to evaluate functionally equivalent alternatives that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

The XRCWHT-L1-0000-002B7 can be substituted with the XREWHT-L1-0000-004E8 based on the following critical compatibility parameters:

Mechanical Compatibility:

• Identical package type: 3529 (9073 Metric)
• Identical physical dimensions: 0.354" L × 0.276" W (9.00mm × 7.00mm)
• Identical maximum seated height: 0.181" (4.60mm)
• Identical mounting type: Surface Mount

Electrical Compatibility:

• Identical test current rating: 350mA
• Similar forward voltage: 4.6V (original) vs. 3.3V (substitute) — within acceptable tolerance for LED applications
• Identical viewing angle: 90°
• Both rated for maximum current of 500mA or higher

Regulatory & Environmental Compliance:

• Both RoHS Compliant
• Both REACH Unaffected
• Both classified under ECCN: EAR99
• Both have MSL 4 (72 Hours) moisture sensitivity

The substitute part represents a newer generation (XR-E series) with improved performance characteristics while maintaining full mechanical and electrical interchangeability in the 3529 package footprint.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The XREWHT-L1-0000-004E8 is suitable as a direct substitute for the obsolete XRCWHT-L1-0000-002B7 in applications where the following conditions are met:

• PCB footprint and assembly equipment are compatible with the 3529 (9073 Metric) package
• Circuit design accommodates the 3.3V forward voltage (0.2V lower than the original)
• Application does not require neutral white color temperature; warm white 2700K is acceptable
• Thermal management design can benefit from the improved thermal resistance (8°C/W vs. 12°C/W)

Product Status Consideration: The substitute part is classified as Active, ensuring long-term availability and continued manufacturing support. The original part's obsolete status makes the XR-E series the recommended path for new designs and production continuity.

Compliance & Certification: Both parts maintain identical RoHS Compliance, REACH Unaffected status, and MSL 4 moisture sensitivity classification, ensuring no change in supply chain handling or environmental compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-004E8 be used as a drop-in replacement for the XRCWHT-L1-0000-002B7?

A: Yes, for applications where the 3529 package footprint is used and the circuit design can accommodate a 3.3V forward voltage (versus 4.6V). The identical package dimensions, mounting type, and viewing angle ensure mechanical compatibility. The 0.2V difference in Vf is within typical LED circuit tolerance ranges.

Q: What is the difference in light output between these two parts?

A: At the 350mA test current, the substitute part delivers 54 lumens compared to 43 lumens from the original part, representing a 25.6% increase in luminous flux. The substitute also provides superior efficiency at 47 lm/W versus 35 lm/W.

Q: Are there any thermal management differences?

A: Yes. The substitute part has a thermal resistance of 8°C/W compared to 12°C/W for the original. This 33% improvement in thermal performance allows for better heat dissipation and potentially higher operating reliability in thermally constrained applications.

Q: Does the color temperature difference affect compatibility?

A: The original part has no specified color temperature, while the substitute is specified as warm white 2700K. If the application requires a neutral or cool white spectrum, this substitute may not be suitable. Color temperature selection depends on the end-use application requirements.

Q: What is the maximum current rating for each part?

A: The original XRCWHT-L1-0000-002B7 is rated for a maximum current of 500mA. The substitute XREWHT-L1-0000-004E8 is rated for 700mA, providing additional headroom for higher-current applications.

Q: Are both parts RoHS compliant?

A: Yes, both parts are RoHS Compliant with identical REACH Unaffected status and MSL 4 moisture sensitivity classification, ensuring no change in supply chain or environmental compliance requirements.

Q: What packaging options are available for the substitute part?

A: The substitute part is supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount assembly operations.
